VoLTE and VoIP are similar technologies. VoLTE or Voice over Long-Term Evolution was invented by a group of companies including Ericsson, Nokia, and Huawei. The technology was first demonstrated in 2010 at the Mobile World Congress by these companies. VoLTE is a digital packet voice service delivered over IP via an LTE access network. It was designed to replace traditional circuit-switched voice calls with a more efficient and higher-quality voice service over the 4G LTE network. The first commercial VoLTE services were launched in 2012 by MetroPCS in Dallas, Texas, in the United States. Since then, VoLTE has become increasingly popular and is now widely used by mobile network operators around the world.
The concept of transmitting voice over the internet, which is the basic principle of VoIP, was first proposed in 1973 by a computer scientist named Danny Cohen. However, it wasn’t until the mid-1990s that the technology became practical for everyday use. The first VoIP application was developed by a company called VocalTec in 1995. VocalTec’s software allowed users to make voice calls over the internet using a microphone and speakers connected to their computer. This technology was initially used for computer-to-computer communication, but later evolved to allow for calls between computers and traditional telephones. Therefore, while Danny Cohen first proposed the concept of transmitting voice over the internet, the first VoIP application was developed by VocalTec in 1995.

Similarities between VoLTE and VoIP
- Voice communication: Both VoLTE and VoIP are used for voice communication, allowing users to make and receive phone calls.
- Data transmission: Both technologies use data networks to transmit voice data, with VoLTE using a 4G LTE network and VoIP using a web-based network such as Wi-Fi or 3G/4G.
- Compatibility: Both VoLTE and VoIP are compatible with a wide range of devices, including smartphones, tablets, and computers.
- Flexibility: Both technologies offer flexibility in terms of where and how users can make calls, allowing users to make calls from anywhere with an internet or cellular connection.
- Additional features: Both VoLTE and VoIP offer additional features beyond traditional voice calls, such as video calling, messaging, and file sharing.
In summary, both technologies are used for voice communication and offer flexibility, compatibility, and additional features beyond traditional voice calls.
The differences between VoLTE and VoIP
While VoLTE and VoIP are both technologies used for voice communication, there are some key differences between the two. Here are some of the main differences:
- Network: VoIP uses a web-based network, such as Wi-Fi or 3G/4G, to transmit voice data, while VoLTE uses a 4G LTE network.
- Quality: VoLTE offers better quality of voice calls than VoIP, thanks to its use of wideband audio that enables voice data to be encoded in high definition.
- Call setup time: VoLTE has a faster call setup time than VoIP, which means that calls can be connected more quickly.
- Battery life: VoLTE uses less battery life than VoIP, which can drain your phone’s battery more quickly.
- Availability: VoIP is more widely available than VoLTE, as it can be used on any device with an internet connection, while VoLTE is limited to devices that support 4G LTE networks.
- Cost: VoIP is often cheaper than VoLTE, as it uses internet data instead of cellular data to transmit voice data.
In summary, VoLTE and VoIP have some key differences in terms of network, quality, call setup time, battery life, availability, and cost. While VoLTE offers better quality and faster call setup times, it is limited to devices that support 4G LTE networks and may use more battery life. VoIP, on the other hand, is more widely available and can be cheaper, but may not offer the same quality of voice calls.
If you forget everything else, remember this
The essential difference between VoLTE and VoIP is the technology it uses. VoLTE is specially designed for 4G LTE networks. VoIP uses any type of Internet connection, be it Wi-Fi, 3G, 4G, or 5G. Note also that VoIP is the older of the two technologies.
